RE: [RPRWG] control TTL
The maximum number of stations on a ring is 255, not 127. I have no idea why
someone changed clause 1; but clauses 8, 9, 10, 11, and E all use a value of
255. And the resolution of comments 155 and 431 support this. The Overview
is informative, and is supposed to reflect a simple summary of what has been
decided in the normative clauses.
(As an aside, while I have no problem with 2000 km as a recommended limit,
I'm also troubled that such technical changes are being made in the Overview
instead of one of the normative clauses. The Overview should be reflecting
what has been decided in the other clauses, not making its own decisions.)

Subject: [RPRWG] control TTL
At the last meeting I had a comment requesting more
information on why the control TTL is 2 bytes. The
explanation provided was that 1 byte is not sufficient
if we have 255 stations and are wrapping. With D0.3,
the maximum number of stations is 127. So now I
don't see a reason for a 2-byte control TTL. I'm
about to submit another comment for this, unless I
can be convinced of a technical reason for a 2-byte
control TTL.
